Recommend to use centralized exchanges is the worst part of your article. It's better if you use decentralized exchanges (e.g. IDEX, etherdelta) since you don't need to submit any personal information to make a purcase.
I don't like submitting personal information as well, but other than that it's a good article. It's good for newbies, they start
with quick explanation about crypto-currencies, how to open a wallet and how to make a deposit. I assume that experienced
people don't have problems with that.
Nitrogen sports is the site I use, what I think is that OP should add more sites. I am sure there's more than 3 casinos where
you can bet on sports with ETH.
